Re: Basic question about filters


You can look into “Multirate Signal Processing” by Fedrick Harris for
details regarding CIC filter, decimators,etc…

Hello everyone:
You see in theory there should be a low-pass filter after ADC for
eliminating the image. Also after DDC there should also be a
filter. But in USRP there are not such things. So do the cic filter and
half band filter implement that function besides decimation?
